WinCC RT Advanced connection to CPU 315 2PN/DP

tx1000

Hi,

I am having problems connecting my WinCC RT advanced to a 1200 plc. When i create an HMI PC station and use an IE general for connection, I connect it to the same PN/IE connection between the PLC and the PC Station. It gives me an error when i select the tags for the PLC address in the GUI setup.

If i setup a SEIMATIC TP1500 or any other HMI panel the PLC tags are automatically imported for use in the GUI. This doesnot happens when i try to setup WinCC RT Advanced to connect to the PLC i get invalid internal tag. If i try to make the connection myself it gives me errors.

Any help would be appreciated. I have read up on other threads here and they were not helpful with regards to this problem.

I have uploaded screenshots.
